It was Neil Taylor who kicked him. Bale was booked for screaming at the ref as he hadn't given Wales a free kick seconds earlier.
I had to laugh at the commentary from our old friend, Barry Horne, who kept banging on about Tadic play acting and causing the collision by ducking down. Even while replays were on showing that to be totally wrong and a fair amount of "claret" pouring out of Dusan's nose.
